Stone mineral slag wool insulation board slab | Wedge India

High Strength | High Temperature Resistant | Low Cost

Mineral wool, also known as stone slag wool, is a type of insulation material made from natural rock, typically basalt or diabase, which is heated and spun into fibers. These fibers are then compressed and formed into various shapes, including batts, rolls, boards, and loose-fill insulation. Mineral wool insulation is valued for its excellent thermal insulation properties, as it effectively reduces heat transfer and helps maintain indoor temperatures. It is also known for its fire resistance, sound absorption, and resistance to moisture, making it suitable for a wide range of applications in residential, commercial, and industrial construction.


Mineral wool insulation is commonly used in walls, roofs, floors, and attics to improve energy efficiency and indoor comfort. It is also used in fire-resistant barriers, acoustic panels, and as a growing medium in hydroponic gardening. Additionally, Mineral wool is considered environmentally friendly as it is made from abundant and recyclable materials. Mineral wool is a type of insulation material made from natural or synthetic minerals, primarily rock or slag. It is commonly used in construction for thermal and acoustic insulation. Mineral wool is manufactured by melting raw materials like basalt, diabase, or slag at high temperatures and then spinning the molten material into fibers. These fibers are then compressed into various forms such as batts, rolls, boards, or loose-fill insulation.

Mineral wool insulation is glass, rock, or slag that has been transformed from a molten condition into a fibrous condition. Mineral wool insulation comes in two varieties. The first is mostly composed of natural stone fibers such as molten basalt or diabase. This variety is made from volcanic rock that has been melted at roughly 1,600°C. This heated rock is then spun into wool and bonded together with various resins and oils. The second is generated from spinning slag, a byproduct of steel manufacture. It may also be derived from natural rock or by mixing it with molten material or even glass. Mineral wool can be used for filtration, soundproofing, thermal insulation,  and seedling germination.
